Can anyone identify this waste level sensor?

Can anyone identify this? Waste water sensor, has 4 wires coming from it. I assume hot, ground and 2 sensor wires. It appears to be copper or copper colored. No floating piece for the waste level. It looks to me like it has a few small silver colored capacitor reading spots up the tube. The bottom has what appears to be a factory cap, so doesn’t look like fluid can go up inside it either. I’ve cleaned it but it still continues to read “half” whether in the tank or out. My waste level reader is the type that has a turn knob to go between waste, water, grey. You push a red button and it will tell you F, H, or E.

I think you described it accurately.

I expected to be able to find it pretty quickly, but no. That technology does not appear in any water leel sensor on Amazon or McMaster-Carr.

I did find one that is similar, although it's not clear that it uses the same technology. Take a look at this:

I've never seen a tank level monitor that even resembles it, plus it appears to be very rusty. I'd replace it. The SCAD tank level monitors are top rated, sensor goes on the outside of any tank material except metal and price is very reasonable.
